LEATHER-SEASONING MACHINE.

Specification of Letters Patent.

Patented June 6, 1916.

To all whom it may concern Be it known that we, WILLIAM E. POIN- sirr'rand J AMES P. POINSETT, both citizens of the United States, residing atWVilmington, county of New Castle, State of Delaware, have invented anew and useful Leather-Seasoning Machine, of which the following is aspecification.

Our invention consists of a novel automatic machine for applyingseasoning, oil or other liquids to skins, hides or leather or similarsheet-articles, in which the liquid is applied to the article andthereupon rubbed or brushed into the surface of the skin.

It further consists of means for alternately rubbing or brushing thecoated skin in opposite" directions.

It further consists of means for impart ing such alternating motions tothe rubbing or brushing elements.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

The annexed drawings and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of various mechanical forms in which the principle of theinvention may be used.

In said annexed drawingsFigure 1 represents a side elevation of ourimproved machine. Fig. 2 represents a longitudinal vertical section ofthe machine. Fig. 3 represents a horizontal section of the machine. Fig.4 represents an end elevation of the machine. Fig. 5 represents a planView of the rocking brush-frame. Fig. 6 represents a detail view of theliquid container and the means for applying the liquid. Fig. 7represents an end-view of the swinging frame carrying the rubbingbrushes.

Similar numerals of reference indicate corresponding parts in thefigures.

ries a worm, 10, which meshes with a wormgear, 11, upon the end of adrum-shaft, 12, longitudinally journaled in the machineframe. A drum,13, is secured upon-said shaft, being composed of hubs, 14, secured uponthe shaft and having radiating spokes, 15, and rims, 16, to which acylindrical drum-shell, 17, is secured. The rims are formed atregistering intervals with peripheral recesses, 18, and the shell isformed with corresponding longitudinal recesses, 19, secured in therecesses of the rims and dividing the circumference of the drum intoequal curved tables or bolsters, 20, upon which the skins to be treatedare spread. Two arms, 21, are pivoted at their inner ends upon thedrum-shaft, outside of the hubs of the end drum-wheels, the hubs, 22, ofsaid arms bearing against the ends of the wheel-hubs, and a shaft, 23,is journaled in the outer ends of said arms, and end-pieces, 24, of alongitudinal frame having side-bars, 25, are pivoted at their middlesupon said shaft. Rods, 26, having rollers, 27 journaled in their forkedinner ends, 28, to bear against the peripheries of two cams, 29, uponthe drum-shaft, are slidable in bearings, 30, pivoted upon the outersides of the rockarms, and said rods are adjustably coupled byscrew-couplings, 31, to rods, 32, pivotally connected to the end-piecesof the rocking frame to rock said frame as the cams raise and lower thebearing-rollers. The cams have preferably one segmental bulge, 33, torock the frame, once for each revolution of the cams, and the cams aresecured upon sleeves, 34, rotatable upon the drum-shaft and havinggears, 35, meshing with idlers, 36, which mesh with gears, 37, uponshafts, 38, journaled in the ends of the machine frame and parallel withthe drum-shaft, which latter gears 37 are connected to pinions, 39, uponsaid shafts, which pinions mesh with larger gears, 40, upon thedrumshaft. Cam-disks, 41, are secured upon the counter-shaft 38 and havecam-grooves, 42, in their outer faces, in which rollers, 43, uponpitmen, 44, engage and travel. The inner ends of said pitmen have forkedheads, 45, which straddle and are slidable upon the countershafts, andthe outer ends of the pitmen are pivotally connected to two levers, 46,the lower ends of which are pivoted upon a longitudinal rod, 48, securedto the side-frames of the machine, and to the upper ends of which arepivoted connectingrods, 49,.the inner ends of which are pivoted to therock-arms 21 carrying the swinging frame.

Upright brackets, 50, extend from the side-frames of the machine and alongitudinally grooved or fluted roller, 51, has the ends of its shaft,52, journaled in hangers, 53, projecting from a bar, 54, parallel withthe drum and supported upon the brackets. A pan, 55, is suspendedbetween the upper portions of the hangers and has an upturned edge, 56,which bears against the fluted roller, being drawn against the latter bysprings, 57, secured to the hangers and pan. The liquid with which theleather is treated, which in the present instance is the so-calledseasoning, is filled into the pan, one side of which is formed by thefluted roller, and when said roller is rotated, it will carry suchliquid with it in its grooves.

A brush-roll, 59, is journaled beneath the trough and roller to have itsbristles contact with the fluted feed-roller. The fluted roller carriesa sprocket-wheel, 60, around which passes a sprocket-chain, 61, passingaround a sprocket-wheel, 62, upon the drumshaft. A sprocket wheel, 83,is revoluble upon the drum-shaft and connected. to the sprocket 62, anda sprocket-chain, 84, passes around said sprocket-wheel and thesprocketwheel 9 upon the shaft 7. The brush-roll has a pinion, 6-3,which meshes with a pinion, 64:, engaging a pinion, 65, upon the shaftof the fluted feed-roller.

Brush-rolls, 66 and 67, are journaled with the ends of their shafts inthe end-pieces of the rocking frame, and one brush-shaft, 68.

of the brush 66 has a sprocket-wheel, 69;

around which passes a chain, 70, which passes around a sprocket-wheel,71, upon a stub-shaft, 72, in one end-piece of the rocking frame, whichsprocket-wheel is connected to a pinion, 73, meshing with a pinion, 7%,upon the shaft 23 journaled in the rocking-- arms. A sprocket-wheel, 75,is secured upon the other end of said shaft and has a sprocket-chain,76, passed around it, which chain passes around a sprocket-wheel, 77,revoluble upon the drunrshaft and connected to a sprocket-wheel, 78,also revoluble upon said shaft and having a sprocket-chain, 79, passingaround it and around the sprocket-wheel, S0, is secured upon the shaft23 alongside of the sprocket-wheel and has .a chain, 81, passing aroundit andv around a sprocket-wheel, 82, upon the shaft of the brush-roll67.

The longitudinal troughs or recesses 19 of the drum are preferablyslightly inclined toward one end of the drum, and a boX or receptacle,83, is supported beneath that end of the drum to receive surplus liquidcollecting in said troughs and flowing out at the ends of the same.

A removable sheetanetal plate, 87, is preferably removably placed ineach trough of the drum to form a concave removable bottom for the same.

A curved scraper-blade, 88, ispivoted. at its ends to bear with its edgeagainst the surface of the drum, and weights, 85, or similarcounter-balancing means, upon arms, 86, projecting outward from saidblade, yieldingly holds-the edge of the latter in contact with theperiphery of the drum to scrape waste treating-liquid. off from thelatter and prevent such waste liquid from contacting with theflesh-sides of the skins and soiling the same.

In practice, the skin, or whatever flat and. sheet-like article is to betreated, is placed upon a table or bolster of the drum which rotates in.the direction of the arrow in Fig. l of the drawings. The skin passesagainst the seasoning or liquid applying brush-roll, the bristles ofwhich are charged with the liquid by the fluted roller which carries theliquid out of the trough to such bristles, and such liquid is applied tothe surface of the skin. The skin travels to the rubbing brushrolls inthe rocking frame which rub the liquid into the skin. The rubbingbrushes rotate in opposite directions so that the liquid will bethoroughly rubbed into the skin and the frame being rocked upon the endsof the arms will alternately bring one or the other of such brushes incontact with the skin. As the rocking frame is moved forward and back asthe skin travels beneath the brushes, the skin is subjected to theaction of the brushes several times while traveling forward, and therocking frame will be at right angles to the rocking arms when therecesses on the drum pass beneath the same, with the brushes out ofcontact with the drum, so that the last treated skin can be freelyremoved. and the next succeed-- ing skin pass freely beneath thebrush-rolls.

The fluted roller takes up the seasoning liquid in its longitudinalgrooves, and. the edge of the trough will scrape such liquid. ofi' fromthe roller, excepting the liquid. within the grooves, which will beremoved bythe brush and applied to the leather. The quantity of liquidcan be gaged by the size and number of longitudinal grooves in thefluted roller, and the quantity of liquid taken up and transferred tothe liquidapplying brusl1-roll will be even, as it is controlled by thesize and. number of grooves which will continually take up and containeven quantities of liquid.

The gearing which drives the oscillating and rocking frame and therubbing brushrollers in the same is so adjusted that the brush-roller incontact with the skin will rotate to brush toward the end of the skin,and that the skin will be held against the surface of the table on thedrum and will not be curled up, as it would be if the rotation of thebrush would be from the ends inward. The rotation of the brush-rollersis so that each end of the skin will be brushed outward from the middleand thus be held against the carrying table.

lVe desire to call special attention to the novel automatic features ofour machine, since it will be apparent that the imparting of asimultaneous rotary and oscillatory movement to the brush rolls 66 and67 simultaneously with the rotation or actu ation .of the skin carrieror drum 13 is entirely automatic, and is performed in unison with therotation of said skin carrier 13 without requiring attention on the partof the operator and all treadles or manually operated devices or thelike are entirely dispensed with. The feature of actuating said brushrolls in the manner described, automatically at the proper intervals,with respect to the rotation of the skin carrier so that each brush rollat the proper periods acts upon the portions of the skin in the mannerdescribed, is one of great impor tance in this art, in practice, and sofar as we are aware, we are the first in the art to construct a machine,wherein said brush rolls have the movements herein described imparted tothem simultaneously and auto matically, by propermechanism common to andcoacting with the movable or rotatable skin carrier.

So far as we are aware, the actuating mechanism common to the movable 0rrotatable skin carrier and the brush rolls, which have the simultaneousrotary and oscillatory movements described, is novel, and our claims tothese various features should be interpreted with the correspondingscope accorded to inventions of this character.

It will be understood from the foregoing that our machine is entirelyautomatic in its operation, and the necessity of the employment of foottreadles or manually operated devices to effect the operation of thebrush rolls and their adjuncts is entirely avoided by our novelconstruction.

While we have described our machine as particularly adapted for use as aseasoning or leather finishing machine, it will be ap parent that in thebroad aspects of our invention, the same is applicable generally to thecoating of any desired material other than leather or the like, and thatother liquids than seasoning or oil may be employed in conjunction withour machine, for coating the desired articles, without departing fromthe spirit of our invention.

It will now be apparent that we have devised a novel and usefulconstruction of a leather seasoning machine which embodies the featuresof advantage enumerated as desirable in the statement of theinventionand the above description, and while we have, in the presentinstance, shown and described a preferred embodiment thereof which willgive in practice satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars without departing from the spirit or scope of the inventionor sacrificing any of its advantages.
